PEBL (software)

PEBL (Psychology Experiment Building Language) is an open source software program that allows researchers to design and run psychological experiments. It runs on PCs using Windows, OS X, and Linux, using the cross-platform Simple DirectMedia Library (libSDL). It was first released in 2003.

Overview

PEBL is a programming language that allows users to create experiments by editing text files. It is written in C++, with a language parser designed using Flex and Bison. It incorporates functions compiled as C++ code that can be used in PEBL, as well as a large number of functions written in PEBL itself.[2][3] PEBL supports presenting stimuli via text, images, movies, audio files; allows response collection via keypress, mouse, joystick, and specialized hardware devices; and supports a number of networking and communication protocols. The PEBL system and related files have been downloaded more than 100,000 times.[4]

Test battery

As well as allowing researchers to develop their own experiments, PEBL includes a set of more than 50 common psychological testing paradigms as part of its Test Battery. Many of its tests have been used and published in peer-reviewed journals.[3][5][6]

These include implementations of:

  • Compensatory Tracking Task
  • Corsi block-tapping test
  • Iowa gambling task
  • Lexical decision task
  • Mackworth Clock
  • Match-to-sample task
  • Memory Span
  • NASA-TLX
  • Psychomotor vigilance task
  • TOVA
  • Tower of London test
  • Trail-making test
  • Wisconsin card sorting task
